I suppose you have Cinnamon installed and running in your computer.
Cinnamon has a Website with themes, extensions and applets. Here is the link for themes:
http://cinnamon-spices.linuxmint.com/themes
You have to download the theme you like and uncompress it in /home/your_user/.themes
If you do not have the .themes folder, you can create it. So you must finally have, for the Minty theme for example, the next path: /home/your_user/.themes/Minty
The Minty folder is the uncompressed theme. Into that folder there is another folder called cinnamon (check this for all the themes you want to install).
Then you will be able to select the theme you installed using Cinnamon Settings (program included with Cinnamon).
The GTK themes are needed for the windows. You can get them from Gnome-look.org, for example. These themes must be installed into the same path (/home/your_user/.themes). Then you can choose the GTK theme in Cinnamon using Cinnamon Settings too.
You can't use Gnome-Shell themes with Cinnamon. You have to use Cinnamon themes.
Sorry for my poor english.

Your claim that
is wrong. GNOME theme include only the gtk themes. The screenshot may include some other programs which may not be part of the theme. For example, the background image also isn't part of the theme.
But if you want to have the icon theme and the launcher, you can follow the steps:
Icon theme
Add the ppa
ppa:noobslab/macbuntu
and install themacbuntu-os-icons-lts-v7
packageI've known from your other question that you're using Zesty, and you needed to use
yakkety
release on the ppa source file. So, in that case, you should be able to installmacbuntu-os-icons-lts-v8
icon instead.Launcher
The launcher is plank. Install it with this command
Install the specific plank theme using this command
You should be able to use the icon theme and configure plank with the specific theme now.
(Same here too. You should be able to install
macbuntu-os-plank-theme-lts-v8
following the advice on your other answer. If you do so, you can have very identical configuration as the screenshot of the theme)
